The amount of the reinforcing member incorporated in the matrix is in the range of from 15 to 45% by weight based on the amount of the matrix. Owing to the use of the reinforcing member which contains carbon nanotubes and carbon nanocapsules, the produced fullerene composite is enabled to acquire improved mechanical strength and resistance to deformation, and the wide applicabilities are endowed with fullerene composites.Other References
